Usually peaceful and not prone to unsolicited attacks, Opo-opos can be dangerous when engaged. Often are found in troops, Opo-opos develop strong social ties, and will assist each other in battle when necessary. With their fast Attack Speed, a troop of Opo-opos can pose quite a challenge for the uninitiated.

Defeated Opo-opos yield little of use for the crafter. The small stature of the creature, coupled with its fast movement during combat, renders its remains torn and useless after battle. As omnivores, Opo-opos can often be found carrying a variety of fruits, which can be gathered by the victorious adventurer.

One of the fruits that can often be found on the carcass of a defeated Opo-opo, and one worth special mention, is Pamamas. Opo-opos appear to derive special benefits from this fruit, and adventurers donning certain specialequipment obtained from Opo-opos can replicate this effect.
